Carbon film resistor has advantages of wide resistance range and good stability, andit is uneasy to be affected by voltage and frequency. In addition, thisresistor is easier to manufacture, having low production cost. Thus, carbonfilm resistors are widely used in the DC and AC circuit of small electronicslike radio, television, calculator, video tape recorder, meters, etc.

Derating CurveBack in 1989, we began producing electronic components and now we own a complete line of manufacturing equipment and hold rich experience applied in the manufacturing of passive components. Shown above is one type of the thin film resistors with various models, and we have other types listed below.
